THE VISCOSITY OF LIQUID MIXTURES
Abstract
The viscosity equation of Collins and Raffel was extended to liquid mixtures and compared to the analogous expressions of Bearman and Rice and their coworkers. Evaluation of the mixture viscosity relation has been made for regular solutions, conformal solutions and the threeliquid model of the solution state. In the last case the interactions between pairs of molecules of the two like species and those of unlike species are handled by application of the law of corresponding states applied separately to each hypothetical liquid. Comparatively simple expressions are then developed for the viscosity of the liquid mixture in terms of one or both of the pure components. The previously developed relations between the shear viscosity and the thermodynamic properties in the special case of the Lennard-Jones and Devonshire intermolecular potential were used in a similar development of the viscosity of the mixture in terms of its thermodynamic properties.
